To be honest this is the conclusion I came to based on the data I am seeing from my own body.
The implication of this though is that the problem is NOT insulin resistance, it's an incorrect calculation by the brain as to what baseline is appropriate. It's interesting in and of itself, from an academic perspective.
Insulin resistance would consist of the pancreas responding to an excess of blood glucose by producing insulin, but that insulin not being taken up by other organs.
But that isn't what is happening here. If it were, the takeup of insulin would be linear, but it isn't.
Fascinating.
As I have said on here previously, the only explanation is that my system "thinks" that 10mmol/l is correct. Otherwise, the process of coming down quickly from near 13mmol/l, but then not going down further wouldn't be possible. Insulin resistance cannot explain this phenomenon - that would be beatable by throwing more insulin at the problem (because the initial reduction is achieved without issue, this proves that the body can indeed regulate down) and would involve bgl eventually coming down. But mine doesn't do that.
